It is a large undertaking for anyone, even for someone with print knowledge. Its difficult doing business like this at long distance, there are so many things that can go wrong. Who is going to get the blame if the job is printed badly?, the guy who picked the printers?, the guy who managed it?. Offset is better quality, thats what you pay for, the skilled human factor!, which opens more doors for error, especially on short runs, when the printer gets bored from doing numerous plate changes. Sorry to be negative, i just know the job. Digital, yes slightly inferior on text, but computerized= no mistakes.
If i where going offset or digital, i would need to be under the noses of the guys printing it. Samples of paper needed, samples of digital black text needed, samples of other similar books they have printed needed. A walk round the factory, if possible?. The printers need to know that they cant produce a bad book for you and that you WILL want it reprinting if it isnt upto scratch. This is why you need to be under there noses. Who is going to pay for a pallet returned half way around the world?, they will argue the toss. All bases need to be covered.
